OVERFLOJV .lkLARMl Application filed May 3,

To all whom t may concern:

Be it known that l, HARRY Gnssnnn, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful lmprovements in Overflow Alarms, ofwhich the following is a specification.

This invention relates to alarms used to indicate when the water levelin a drip pan or similar receptacle has reached a predetermined level.As well known the overflow of a drip pan beneath an ice boX causesconsiderable damage and also prevents the tidy 11p-keep of suchquarters.

Another object is the provision of a device as described which iscontrolled by a float and a means for adjusting the latter to suitvarious conditions such as a larger or smaller sized drip pan or similarother reasons.

These and other objects will become apparent in the description below inwhich characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing; Figure 1 indicates a top plan view ofthe device showing cover member cut away so as to show the alarmactuating mechanism.

Figure 2 is a sectional front elevational view taken on line 2--2 ofFigure 1. Y

Figure 3 is a side elevational view of the device showing means forextending the Heat and means for securing the device to a receptacle.

Describing the drawing in detail the numeral 10 indicates asubstantially square body plate which has the backs 11 of clamp jaws 12formed integral therewith. Space 13 between the said jaws 12 receive thevertical wall 141- of whatever receptacle or drip pan is being used. A.screw 15 threadable in one of the jaws lrrigidly secures the device tothe above said wall 14: and prevents the saine from being` broken byfalling or other wise becoming inoperative.

An angular upstanding bracket 16 is secured to plate 10 has an arm 17pivoted thereon, the latter extending horizontally out of the chamberformed by the casing 18. Ears 19 projecting upwardly at the corners ofbody plate 10 receive the threaded ends of screws .20 which retain saidcasing 18 rigidly in place on the said plate 10.

Serial No. 558,146.

An upper frame 21 and a lower 22 form means for journalling a verticalspindle 211 upon which a toothed wheel and a pinion Q6 is mounted. Thelatter lies in mesh with a gear wheel 27 which is rotatably mounted onshaft 28 the latter having one end of a spiral spring Q9 secured theretowhile its opposite end is fixed to the post 30. The usual ratchet wheel31 and pawl 32 engaging the latter, are provided on the shaft 28 and akey 33 surmounting the said shaft provides a means for winding thespiral spring.

The said spindle 25 has pallet arms 34: which alternately engage thetoothed wheel Q3 and vibrate the extending arm 35. The latter isprovided with a striker 36 which will contact the sound disk 37.

A locking lug 38 forming an extension of arm 17 engages the striker armwhen arm 17 is at its lowest position.

rllhe end of said lever arm 17 pivotally receives a hollow rod 33 whichis provided with a longitudinal slot 39 having a series of semi-circularnotches 410 cut on one side thereof.

A hollow spherical float l1 has a radially disposed stud 4t2 rigidlymounted thereon7 the latter being insert-able in rod 38 and has a pin413 projecting from the side which engages any of the notches el() andretains the float in any of the adjusted positions.

ln use the device is secured to a receptacle by slipping the clamp aws12 over the wall and adjusting the members 15.

rThe iloat arm 38 is rotated to any angle desired depending on the levelat which the alarm is to be given. l-idditional and finer adjustment isaccomplished by engaging any of the various notches 10.

As the level of the water rises the float l1 will be buoyed up by thepressure of the water.l until. the locking lug 38 is disengaged from thestriker bar 35 which permits the vibration of the striker head 36against the surface of the sound disk 37 thus giving an audible signalthat the liquid has risen to the predetermined level. A

Turning the winding key will retention the spiral spring 29 after thelatter has been used.

claim A device of the class described comprising, a body plate andcasing member thereon7 a striker membei1 in said easing, a disk mountedadjacent said striker, said disk adapted 'to give an audible alarm whenthe striker is vibi'ated, a lever arm pivoted in said easing having alocking lug engaging said. strikei' when said lever is in lowermostposition, a hollow rod pivoted at the end of mid lever, a 'float member,a stud thereon, said stud sldable in thehollow rod, means for 'vibratingsaid striker When the level` 10 arm is lifted and means for securngthedevice to a receptacle.

In witness whereof I aflxmy signature.

HARRY GESSLER.
